What does this PR aims to accomplish

Bump Fedora to 41.... just that... easy ain't it...

I am trying to avoid changing the management_dispvm on a per qube basis of Fedora based qubes... but for that to happen, the dependency ordering has to be enforced. For example, to even get to tpl-qubes-builder, it is a huge burden:

1. fedora-xfce: because a dvm of it will server for fedora-minimal
2. fedora-minimal: because mgmt and qubes-builder will be based from it
3. mgmt: because it is better to enforce having a fedora based mgmt qube
4. qubes-builder: now we are here...

What does this PR change

• Increase Fedora version
• Remove python3-urllib workaround
• Depend on fedora-xfce (current upstream default template) instead of old default template fedora
• Update package names on newer Fedora (TODO)
